Mexican researchers designed and developed a technology package for the detection of precursor lesions by human papillomavirus (HPV), which may cause cervical cancer. If HPV is present in the patient, it can be completely eradicated if timely detected. The use of this system provides for early, accurate, non-invasive diagnosis, in less time and at a lower cost.
José Gerardo Zertuche explained the technological achievement combines the medical part, the analysis of images and the computer diagnosis. Is composed of an actinic light colposcope and uses an optical filter for selective excitation and detection of fluorescence, and a piece of software that captures the images of the cervix and stores them creating an electronic clinical file.
The objective of the technological package, said Dr. Zertuche is to facilitate the diagnosis. “What we did was modify some filters so that, by placing a solution in the cervix, we get a dark image that will mean that it is healthy or, if it turns out to be a green color, there is an injury.”
This Mexican system uses a camera that is inserted with a vaginal speculum to acquire a complete image of the cervix, unlike the Papanicolau that extracts a sample.
Juan Manuel Peña Aguilar, explained that one of the advantages of this system is that allows diagnosing the patient in a single medical visit, unlike the current procedures that need waiting for lab results.
In the same way, it is important to emphasize that the system is suitable for use in communities of difficult access. With this system, the images obtained can be easily read not only by a doctor, but also by a trained technician or nurse.
Currently the equipment already has a national patent and is in process to obtain patents in the United States and in Germany. It already works in two hospitals of the country: one located in Tuxtla Gutiérrez, Chiapas, and another one in Mexico City. “The technology has facilitated the diagnosis; and we would like to have more support for this innovation to have greater coverage,” emphasized Dr. Zertuche.
This innovation won the first place in the Mexican Association of Applied Research and Technological Development (ADIAT) Award to technological innovation in 2017.
